Whats the general res that morphos users use?
They should use the native resolution of the monitor
I myself use 1920x1080 (fullhd) and 1600x1200 resolutions mostly. No problems setting them with real monitors.. although I've had some problems getting optimal resolution for TVs.. they seem to be more picky.
I am using a hdtv/vga mointor tv thing
Its a goodmans LD1945WDW could not find it on the list and cannot find any reference to the khz online, do you think I will have to just try a few monitors on the list to see if they work with it?
Also when I select the monitor will the modes list update with new avaible modes or do I have to add new ones manually?
That display seems to have 1440x900 as native resolution, so you should try to get that displayed.
Most likely you should find that resolution on pre-defined mode list when you're creating new mode in Monitors prefs (if not, pick the closest one for example and edit it suitable with resolution and pixel clock settings). Select it on Edit Mode window, select 24bit and hit Test button. If it displays fine click OK and Save. Then you should be able to select that mode for Ambient screen in Screens prefs.
